Xylella fastidiosa Differentially Accumulates Mineral Elements in Biofilm and Planktonic Cells
Xylella fastidiosa is a bacterial plant pathogen that infects numerous plant hosts. Disease develops when the bacterium colonizes the xylem vessels and forms a biofilm. Inductively coupled plasma optical emission spectroscopy was used to examine the mineral element content of this pathogen in biofilm and planktonic states. Significant accumulations of copper (30-fold), manganese (6-fold), zinc ...
متن کاملThe Secreted Protease PrtA Controls Cell Growth, Biofilm Formation and Pathogenicity in Xylella fastidiosa
Pierce's disease (PD) is a deadly disease of grapevines caused by the Gram-negative bacterium Xylella fastidiosa. Though disease symptoms were formerly attributed to bacteria blocking the plant xylem, this hypothesis is at best overly simplistic. Recently, we used a proteomic approach to characterize the secretome of X. fastidiosa, both in vitro and in planta, and identified LesA as one of the ...
متن کاملTHE ROLE OF LIPOPOLYSACCHARIDE IN VIRULENCE, BIOFILM FORMATION, AND HOST SPECIFICITY OF XYLELLA FASTIDIOSA Principal Investigator:
This project aims to further elucidate the molecular mechanisms Xylella fastidiosa (Xf) employs during the infection of its host. We are focusing on the lipopolysaccharide (LPS) component of the outer membrane of Xf. LPS contains a conserved lipid A and core portion and a variable O-antigen portion. In particular, we are examining the variable portion of the LPS molecule, the O-antigen. O-antig...
متن کاملTHE ROLE OF LIPOPOLYSACCHARIDES IN VIRULENCE, BIOFILM FORMATION, AND HOST SPECIFICITY OF XYLELLA FASTIDIOSA Principal Investigator:
This project focuses on the lipopolysaccharide (LPS) component of the outer membrane of Xylella fastidiosa (Xf). In particular, we are investigating if the O-antigen portion of this molecule contributes to Xf surface attachment and biofilm formation. More importantly, by targeting genes involved in O-antigen biosynthesis, we will determine if LPS is an important virulence factor for Xf infectio...
متن کاملSpatiotemporal distribution of different extracellular polymeric substances and filamentation mediate Xylella fastidiosa adhesion and biofilm formation
Microorganism pathogenicity strongly relies on the generation of multicellular assemblies, called biofilms. Understanding their organization can unveil vulnerabilities leading to potential treatments; spatially and temporally-resolved comprehensive experimental characterization can provide new details of biofilm formation, and possibly new targets for disease control. Here, biofilm formation of...
